Part Number: SN65HVD37 Hi team,
My customer is using SN65HVD37DR in their new design.
They recently found that the device's Voh min=2.4V＠Ioh=-8mA, which is lower than the MCU they are using, with Vih=2.7V.
The board is already fixed and there's…

Hi team,
My customer is wondering if they can use this device with half duplex communication. I guess it can't be used for half duplex, it is correct? If it can be used, is there any…
Part Number: SN65HVD37 Hi team.
My customer is designing the layout for SN65HVD37DR.
I guess they have to care about below:
Parallel/equal-length wiring for receiving side A, B and transmitting side Y, Z, respectively.
Receiver A,B and Transmitter…
Part Number: SN65HVD37 Hi Team
My customer have 2 questions about SN65HVD37.
Please kindly help with these. It will be appreciate.
1. Datasheet says VOH(min) is 2.4V on Pin 2(Receiver) when IOH=-8mA.
Customer wants to connect Pin 2 to another…
Hi Adrain,
Thanks for your reply.
My application is to use RS485 for communication between my HMI(Human Machine Interface) and PLC .So i need a protection for RS485 so that my HMI is not affected by any kind of noise or interruption from the PLC while…

Other Parts Discussed in Thread: SN65HVD37 Hi,
I understand SN65HVD37 meets TIA-485-A specificaitons.
So, should the value of Termination be 120Ω ?
In case of SN65HVD37, how much power is Termination(120Ω) consumed ?
Best Regards,
Kato
Ohashi-san,
No issue - I answered your other thread here: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1200444/sn65hvd37-about-layout-guideline if you need anything else please let me know!

Brian,
Unfortunately THVD2450 has no full duplex version. In this case, you may want to check out SN65HVD37. Here is an app note showing its performance.
